About the company
Particle Instruments LLC, a for-profit limited liability company based in St. Paul, Minnesota, sells specialized aerosol particle measurement and analysis instrumentation to federal agencies as a prime contractor on firm-fixed-price purchase orders, with no small business set-asides across its federal portfolio.
Particle Instruments operates exclusively as a prime on government procurements—all 57 awards in the source are prime contracts, none subcontracted. The vendor's core capability is the procurement and delivery of high-resolution electrical low-pressure impactors (ELPI and ELPI+), field calibration systems, condensation aerosol generators, and related particle-sizing and aerosol diagnostic equipment. Representative recent work includes a $136,955 high-resolution low-pressure impactor delivered to CDC Pittsburgh (August 2026, completion August 2027); a $106,530 Dekati ELPI+ electrical low-pressure impactor procured by EPA Office of Research and Development (June 2024, completed July 2024); a $101,670 high-resolution electrical low-pressure cascade impactor for the National Institute of Standards and Technology (March 2023, completed May 2023); and a $106,530 electrical low-pressure impactor delivered to NASA Shared Services Center (September 2023, completed October 2023). The vendor also supplies replacement parts and software upgrades for installed equipment, such as a $10,700 high-resolution software and hardware upgrade for an ELPI+ lab instrument at NASA (May 2025).
Customer concentration sits primarily with health and environmental agencies. CDC Pittsburgh alone accounts for 15 awards ($682 thousand combined potential value) and represents 27% of total awards; NASA Shared Services Center follows with 7 awards ($273 thousand); and NIST, EPA Office of Research and Development, and FDA collectively represent the next tier of activity. Together, CDC Pittsburgh, NASA, and NIST cover 54% of all awards and 65% of combined potential value. The vendor serves 21 distinct federal agencies across the dataset, with no parent IDVCs or vehicle-based ordering pattern; all awards are direct purchase orders under simplified acquisition thresholds.
Activity has remained stable at two awards per year across 2024, 2025, and 2026, with 57 total awards spanning from 2003 to August 2026 and a combined potential value of $2.1 million (actual obligations reached $2.2 million). Only one award faces recompete in the next twenty-four months ($137 thousand potential value). Particle Instruments' NAICS profile centers on analytical laboratory instrument manufacturing (18 awards) and professional equipment and supplies merchant wholesale (20 awards), with PSC coding concentrated in laboratory equipment and supplies (34 awards). The vendor does not maintain subcontractor relationships; all work is performed directly or sourced from equipment manufacturers (such as Dekati) that Particle Instruments procures and delivers to end-user agencies.
